For 2009-10, 38 Littles were recorded at 26 wetlands (mainly southeast and southwest mainland Australia); 94 Australasian Bitterns were recorded in 63 wetlands (mainly southeast and southwest, and Tasmania). No estimate is offered of total Littles. 'Threatened' status is sought for Australasians, which may number fewer than 1000 (NZ has 500-2000).
I am certain many more Littles are out there. But being smaller, quieter and living farther from birding hotspots means fewer reports. The surveys continue.
No shortage ever of White-browed Crakes (Amaurornis cinerea) in Tyto, though high lagoon levels mean many are stalking unseen through reeds and fewer are out treading the lily leaves.
